eEtherification: An Electrochemical Strategy toward the Synthesis of Sterically Hindered Dialkyl Ethers from Activated Alcohols

This is the authors' abstract. We don't add key points for this paper.

Traditional etherification methods, although staples in synthetic chemistry, often fall short in the efficient construction of sterically hindered dialkyl ethers, especially under mild and practical conditions. Recent advances have attempted to address these limitations, typically relying on transition metal catalysts, external reductants, or harsh reaction conditions. In this work, we disclose a novel electrochemical approach that enables the synthesis of sterically hindered ethers from economically relevant and readily accessible alcohols without the need for sacrificial oxidants. Our protocol exploits mild conditions to generate reactive carbocations, which are subsequently captured by alcohol nucleophiles to yield the desired ethers. This method is cost-effective, practical, and broad in scope, providing a valuable addition to chemists' synthetic toolkit for ether synthesis.
